Gershom

[1] The name means "a stranger there" in Hebrew, (גר שם‎ ger sham), which the text argues was a reference to Moses' flight from Egypt.

The possibility that the story of Micah's Idol refers to immediate descendants of Moses being priests is taken by biblical scholars as a demonstration that the Aaronim-only restriction was originally not present in the Israelite priesthood.

The Bible recounts very strict lineage rules for the priests, aka "the descendants of Aaron", but certain deviations from the concept are mentioned – for instance, prophets such as Samuel or Elijah performed priestly-like services in special cases.

As mentioned above, it is probable that Gershom's lineage would have compelled him into the priesthood, yet it appears he performed no regular priestly services of note.

In other related writings it is mentioned that God ordered Moses to pass authority unto Joshua instead of his own two stubborn sons, Gershom and Eliezer.
